The Income Tax Department (ITD) has introduced a new compliance measure to enhance tax transparency and curb discrepancies in income declarations. Starting this financial year, the department will compare your last year’s Income Tax Return (ITR) with the current year’s ITR to detect any irregularities, inconsistencies, or mismatches in reported income, deductions, and tax liabilities.

This move aims to reduce tax evasion, improve compliance, and ensure accurate reporting by taxpayers. But how will this impact you as a taxpayer? What are the risks of discrepancies, and how can you avoid penalties or scrutiny?

The Finance Bill 2025, recently passed in the Lok Sabha, includes an amendment to Section 143(1) of the Income Tax Act, 1961. This amendment mandates the comparison of the current year’s ITR with the previous year’s ITR to detect any inconsistencies. The Income Tax Department has released FAQs to clarify the specifics of this new measure.

What is Section 143(1) of the Income Tax Act?

Section 143(1) deals with the processing of income tax returns after they are submitted and verified by the taxpayer. Currently, the department checks for arithmetical errors and incorrect claims apparent from the information in the return. The new amendment expands this scope to include a comparison with the previous year’s ITR.

In this comprehensive guide, we’ll explore:

• Why the IT Department is comparing ITRs
• How the comparison will be done
• Key areas where discrepancies may arise
• Impact on taxpayers (salaried, business, freelancers)
• How to avoid mismatches and penalties
• Latest updates and compliance tips

Why is the Income Tax Department Comparing Last Year’s ITR with Current Year’s ITR?

The primary objective of this comparison is to ensure that taxpayers report their income accurately and consistently. By comparing the current year’s ITR with the previous year’s ITR, the department can identify discrepancies that may indicate underreporting of income or overclaiming of deductions.

The Central Board of Direct Taxes (CBDT) has been leveraging advanced data analytics, artificial intelligence (AI), and automation to detect tax fraud and underreporting of income. By comparing ITRs year-on-year, the tax authorities can:

✅ Identify sudden drops in reported income (e.g., a taxpayer reporting ₹15 lakh in FY 2022-23 but only ₹8 lakh in FY 2023-24 without valid reasons).
✅ Detect inflated deductions or exemptions (e.g., exaggerated HRA claims, medical expenses, or Section 80C deductions).
✅ Uncover undisclosed income sources (e.g., unexplained deposits, cryptocurrency gains, or foreign assets).
✅ Reduce tax evasion by flagging inconsistencies in business turnover, capital gains, or rental income.

According to the CBDT Annual Report 2023-24, over 1.12 crore cases were flagged for discrepancies in the last fiscal year, leading to ₹48,000 crore in additional tax demands.

How Will the IT Department Compare ITRs?

The tax department uses an automated system that cross-verifies:

🔹 Gross Total Income (GTI) – A sudden drop or spike may trigger scrutiny.
🔹 Tax Deducted at Source (TDS) & Form 26AS – Mismatches between TDS credits and declared income.
🔹 Deductions (Chapter VI-A) – Excessive claims under Section 80C, 80D, 80G, etc.
🔹 Capital Gains – Discrepancies in stock market, mutual funds, or property sales.
🔹 Business Income – Unexplained fluctuations in GST turnover vs. ITR filings.
🔹 Bank Transactions – High-value deposits (via Annual Information Statement – AIS).

If the system detects abnormal variations, the taxpayer may receive an income tax notice under Section 143(1) or 139(9) for clarification.

Key Areas Where Discrepancies May Arise

1. Salary Income Mismatch

• If your Form 16 income differs from ITR declarations.
• Example: You reported ₹12 lakh in FY 2022-23 but only ₹9 lakh in FY 2023-24 without job loss or pay cut.

2. Business & Freelancer Income

• GST turnover vs. ITR income mismatch (e.g., ₹50 lakh in GST filings but ₹30 lakh in ITR).
• Sudden drop in profits without valid reasons.

3. Capital Gains & Investments

• Unreported stock market profits, crypto gains, or mutual fund redemptions.
• Property sales not reflected in ITR.

4. Deduction Claims (Section 80C, 80D, HRA, etc.)

• Exaggerated medical insurance claims (80D).
• False HRA claims without rent receipts.

5. High-Value Transactions (AIS & TIS)

• Cash deposits over ₹10 lakh.
• Unexplained credit card spends or foreign trips.

How Taxpayers Will Be Impacted?

1. Increased Scrutiny & Notices

• Taxpayers with discrepancies may receive automated notices under:
  • Section 143(1) – Intimation for mismatches.
  • Section 139(9) – Defective return notice.
  • Section 148 – Income escaping assessment.

2. Penalties & Additional Tax Demand

• Underreporting income may attract 50% to 200% penalty under Section 270A.
• Interest under Section 234A/B/C for late tax payments.

3. Impact on Refunds

• Refunds may be delayed if discrepancies are found.
• Revised ITR filing (ITR-U) may be required.

4. Business & Freelancers at Higher Risk

• GST and ITR data matching may lead to tax audits under Section 44AB.
• Freelancers must ensure Form 26AS and 1099 (for foreign clients) match ITR.

How to Avoid Discrepancies & Penalties?

1. Cross-Check Before Filing ITR

• Match Form 26AS, AIS, and Form 16 with your income.
• Verify bank statements, capital gains, and deductions.

2. Maintain Proper Documentation

• Rent receipts for HRA.
• Medical bills for Section 80D.
• Investment proofs for Section 80C.

3. File Revised ITR (if errors found)

• Use ITR-U (Updated Return) within 2 years if omissions exist.

4. Respond to Notices Promptly

• Ignoring notices may lead to best judgment assessment (Section 144).

5. Use Professional Help

• CA or tax consultant can help reconcile discrepancies.

Latest Updates (2024-25)

🔹 AIS (Annual Information Statement) now includes crypto, foreign remittances, and mutual funds.
🔹 New 26QB compliance for property buyers (TDS on real estate).
🔹 Stricter HRA verification via rent payment trails.

Final Thought

Pro Tip: Always reconcile your income, deductions, and TDS before filing ITR. If discrepancies exist, file a revised return or seek professional advice.

The Income Tax Department’s move to compare last year’s ITR with current filings is a game-changer for compliance. Taxpayers must ensure accurate reporting, proper documentation, and timely responses to avoid penalties. The comparison of last year’s ITR with the current year’s ITR is a significant step towards enhancing transparency and ensuring accurate tax reporting. While this measure may increase scrutiny and require more diligent record-keeping, it ultimately aims to create a fairer tax system. By understanding the implications of this new measure and taking proactive steps to prepare, taxpayers can ensure compliance and avoid potential penalties.
